AGU-SEG HYDROGEOPHYSICS WORKSHOP
• STANFORD –CALIFORNIA
• 24-27 JULY 2017

Welcome


The Critical Zone (CZ) is a dynamic region where rock, soil, water, air, and living biota interact to shape Earth’s surface. The Critical Zone ranges from the tops of the trees to the bottom of groundwater. The field of hydrogeophysics employs geophysical methods to determine parameters and monitor processes associated with water resources, the water cycle, and contaminant transport to inform hydrogeological studies. All of CZ science could benefit from the temporal and spatial information provided by hydrogeophysics; however, to date the two fields have evolved largely in parallel. In this workshop, we propose to develop a framework for advancing both hydrogeophysics and CZ science through communicating and coordinating research agendas. New insights into CZ processes will be gained through the enhanced use of hydrogeophysics, and the detailed interdisciplinary observations made in CZ studies will provide opportunities for advancing hydrogeophysical methods.
Specifically, in this workshop, we aim to:


1. bring together hydrogeophysicists and other CZ scientists to inform and exchange ideas,
2. identify the critical areas of future research to optimize the use of hydrogeophysics for CZ science, and
3. write a white paper identifying research focus areas for CZ-geophysics.

We invite abstracts for the four sessions described below. Abstracts must be less than 2000 characters, excluding spaces but including punctuation. The sessions for the workshop have been designed to bring together hydrogeophysicists and other CZ scientists to exchange ideas and identify the critical areas of future research that will allow us to optimize the use of hydrogeophysics for CZ science.
Each session will begin with two invited talks – one hydrogeophysicist and one CZ scientist. All other presentations will be as posters. Before the viewing of posters, there will be an oral session where each presenter has 3 minutes to introduce their poster. After the viewing of posters, there will be a panel-led discussion.
The preliminary program is given here. Note that in order to encourage the exchange of ideas and development of new collaborations, we will have all lunches and one dinner together. In addition, on Wednesday afternoon we will select research challenges from the CZO community and have interdisciplinary groups work on how to apply geophysical techniques to these problems. We hope this will be a way to further communication between the two groups and hopefully fertilize some new and exciting research ideas.

Session 1:
Interfaces in the Critical Zone. Interfaces in subsurface properties have a strong influence on the physical, chemical, and biological processes that occur in the CZ. Near surface geophysical methods can be used to image these interfaces, but data-fusion and interpretation challenges, remain. Measurements of fluxes across interfaces often rely on indirect methods, further challenging the use of models to integrate geophysical data with hydrologic and geochemical measurements to understand interface behavior. In this session, we encourage contributions that focus on both the quantitative delineation of interfaces in the CZ and the role of imaging combined with monitoring of interfaces in addressing CZ science questions. Submissions related to the following are encouraged: physical, chemical and hydrologic processes driving exchange within or between critical zone interfaces, including the root zone, soil and/or weathering layers, hydrostratigraphy, bedrock, permafrost and thermokarsts, and fractures. The discussion will focus on opportunities and challenges associated with imaging interfaces and quantifying interfacial fluxes in the CZ through measurement and modeling.

Session 2:
Hydro-bio-geo-chemical processes in the Critical Zone. The flux of fluids or gases and their constituents in the subsurface drives biogeochemical processes at a variety of timescales. How can hydrogeophysical methods can be used to track temporal changes in these processes? In this session, we encourage contributions relating to fluid and gas fluxes as measures or drivers of biogeochemical processes, the implementation of hydrogeophysical techniques to track the temporal dynamics of CZ processes and model frameworks that integrate both. Topics of interest include: gas and solute transport, fluid mixing, microbial processes, evapotranspiration, carbon cycling, mineral precipitation, snow hydrology, surface-ground-water interactions, disturbance/land use practices, aspect control on vegetation and water balance.

Session 3:
Critical Zone properties & rock physics. As CZ science continues to cross disciplinary boundaries, hydrogeophysicists are challenged to understand the geophysical responses to a diverse suite of parameters that extend beyond rock and fluid properties. Additionally, the complexity of the CZ challenges some of the fundamental simplifying assumptions underlying traditional rock-physics relationships. In this session, we encourage contributions related to measurements of CZ properties and advancesapproaches.

Session 4: in the interpretation of geophysical parameters at the field scale from experimental and theoretical work. Topics of interest include quantifying subsurface biomass, quantifying microbial respiration, identifying clay minerals, predicting vadose zone parameters, and predicting hydrogeological parameters, as well as the integration of the above through modeling
Scaling of Critical Zone data to address science questions. The value of collecting physical, geochemical and hydrogeophysical data in the CZ is primarily realized when the data can be scaled appropriately and included in other datasets to elucidate the larger picture CZ processes. What types of physical, geochemical and hydrogeophysical data are complementary and facilitate scaling? What are the barriers to evaluating upscaled physical, geochemical, and hydrogeophysical data? While scaling will likely play a role in the other three themes/sessions, in this session, we encourage submissions focused specifically on the development of strategies for the up- or down- scaling of CZ data and for the inclusion of scaled data in CZ studies. We seek case studies – both successful and unsuccessful – in which hydrogeophysical and/or other
